44. Transmission temperature
warning indicator illumi-
nates during vehicle opera-
tion when transmission is
not overheated (indicator
illuminates normally during
engine start-up lamp test).
1. Wiring is shorting to ground.
2. Defective transmission
temperature sender.
1. If the indicator continues to
illuminate, check the wiring from
the operators display panel to the
ignition key switch, fuse panel
and sender for a short to ground.
If a short is detected, test the
circuit and repair the short.
2. Disconnect wiring connector at
the transmission temperature
sender switch on the
transmission. If the wiring checks
out o.k. and the transmission
temperature warning indicator
continues to illuminate, install a
new transmission temperature
sender switch. If the problem
persists, replace the operators
display panel. Test and replace
the sender as required.
45. FUEL LEVEL INDICATOR
BARS
No indication.
1. No current in circuit because of
broken or disconnected lead.
2. Bad ground connection.
3. Defective fuel level sender at fuel
tank.
4. Defective operators display panel.
1. Check wiring and repair or
replace as required. Follow wiring
from sender on fuel tank beneath
cab to fuse panel, ignition key
switch and operators display
panel terminal for fuel level
indicator bars.
2. Repair ground.
3. Check for proper resistance; see
Section 10.8.25 Fuel Level
Indicator and Fuel Level Sender.
4. Replace panel.
46. Excessive fuel level indica-
tor bar fluctuation (not
caused by frame tilt func-
tion, travel over rough ter-
rain, etc.).
1. Loose wire connections.
2. Defective fuel level sender at fuel
tank.
1. Tighten connections at fuel level
sender.
2. Test. If bad, replace sender.
47. FULL reading at all times. 1. Wire #27 BRN/GRN to sender is
shorted to ground.
2. Defective fuel level sender at fuel
tank.
1. Repair short.
2. Test. Replace if defective.
48. Fuel level indicator bars
indicate inaccurately.
1. Defective fuel level sender in tank.
2. Low voltage at fuel level sender
(should read 33.5 ohms for a full
tank of fuel and 240 ohms for an
empty tank).
1. Replace fuel level sender in tank.
2. Check ohm reading. Determine
and correct cause of low voltage.
